UNITED Iii PATENT @rrr IMPROVEMENT IN PEN-HOLDERS.

Specification forming part of Letters Patent No. 187,238, dated February13, 1877; application filed July 12, 1876.

To all whom it may concern:

Be it known that I, DANIEL M. Serums, of the city, county, and State ofNew York, have invented an Improvement in Pen-I-Iolders, of which thefollowing is a specification This invention consists in a novelconstruction of pen-holder tips, the nature of which is fullyillustrated in the accompanying drawings, as will be particularlyhereinafter described.

Pen-holder tips of the general construction to which my inventionappertains have here tofore been made of a solid tube of metal, havingone end swaged or bent inwardly toward one side so that its walls,nearly meeting, shall form a semicircular opening to receive and holdthe pen. The outer edges of these walls are, however, usually filed orotherwise dressed ofl' even, so as to form eoineiding edges, whichconstruction renders it inconvenient and laborious to insert the pen.

In my invention one, either the outer or inner, wall of such a tip isextended, as at 1, Fig. 5, to present a guiding-lip to assist the readyinsertion of the pen. In order to facilitate the ready entrance of thepen,as well as to furnish it when inserted with an elastic hearing,which shall render its union with the holder flexible or somewhatyielding, I provide it with spring-nibs 2, by dividing the inner wall 3by means of a slit or slot, 4, extending a suitable distance from itsextreme end. The said spring-nibs 2 are independently movable, and bytheir resiliency bear upon the opposite edges of the pen with a pressurewhich permits its ready introduction, and also firmly holds the insertedpen in its proper adjustment.

Where considerable strength is required, the spring-nibs 2 may be joinedat their rear ends by a brace, 5, which is formed by cutting asemicircular slot through the inner wall, as shown in Fig. 1, and thisbrace 5 will usually be bent down so as to form a spring-lip, 6, (seeFig. 2,) which will bear upon the inner surface of the pen at its rearend, and thus provide a third spring-bearing, securing it firmly inplace. The strength of the springnibs 2 may also be augmented by swaginga projection, 7 inwardly, which corrugation of the metal will impart aconsiderable stiffness to them, and this projection 7 may be forced infar enough to act as a stop, limiting the entrance of the pen, or so asto operate :as a rib, which will press the pen more tightly against theinner surface of the upper wall of the tip, and thus bind the. pen moresecurely in place.

It is to be observed that this improved tip provides for clamping thepen at three points, viz: on each side and upon its rear end, the tip 6or the projection 7 serving, in connection with the spring-nibs 2, tothus secure it firmly in place.

The tip may be formed either from a solid tube, as has thus far beendescribed, or from a tube made by bending a flat plate of metal intotubular forms, as in Fig. 4. In this construction the tube end is bentinwardly, to bring its walls into close proximity, as in Fig. l, and theinner wall is cut transversely, as at 8, to form the spring-tongues 2.

While I have divided the splitting of the inner wall of the tip to formthe spring-nibs 2, I wish it understood that the same may be provided bysplitting the outer wall in like manner, and also that it is quiteimmaterial whichbf the two walls is projected to form the lip 1.

What I claim as new isl. A pen-holder tip consisting of a tube havingone end bent inwardly to form double walls, which provide a pen-recessbetween them, one of which walls is solid while the other is splitlongitudinally to form springnibs, substantially as described.

2. A pen-holder tip consisting of a tube having one end bent inwardly toform double walls, which provide a pen-recess between them, one of whichwalls is split longitudinally to form spring-nibs, and also providedwith a transverse inward projection, as 6 or 7, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DANIEL M. SOMERS.
